I considered the same thing once and test drove one that a funeral home was selling. I totally understand the appeal and they drive sooo smooth but I went with a van instead. I do a ton of miles when I’m out and even a older van doesn’t work best for me but damn do I miss the space of van. Gas miles, reliability to lay down the miles is key for me along with being able to sleep.. Also, staying stealthy and off the visual radar. I get it through but personally if I going to be doing any longtime miles I’d find another way.
